So these are not grey market or anything. GMG do sell some games sourced not directly from the publisher in some instances.
I'd be curious to hear more about what policies Epic have related to this, my main questions would be:
Are there any restrictions on where publishers can sell codes?
Are there any restrictions on the amount of codes offered?
Are there any restrictions on or policies related to pricing?
Is this something that is offered to all Epic Store games going forward?
Do Epic charge anything for these keys?
This is good progress.
